I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

Neil, I hadn't thought of it that way-- it would save money, only have to run one wire to each midbass too! You're too funny! The link Romy posted earlier: http://www.6moons.com/industryfeatures/vsac20082/vsac.html shows the throat.&...

I was thinking about a space-economical way to arm playback with midbass 50Hz horn. It is not that I am into it myself but conceptually I was wondering how to put all of necessarily things within a minimum compromise in minimum footprint. I came up w...

This is very interesting, I was thinking of such an option given the existence of a basement, (I do not have that luxury, but I have a concrete slab).
The idea that the driver is actually closer to the...

[quote user="Kcct82"]Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.
I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret with...

As some of your might know I am not huge in Mahler. It is not that I hate Mahler and his music but I do not like how Mahler music is customary being played. They play Mahler like it is some kind of scared porcupine, sticking out his needles; I do not...

[quote user="Romy the Cat"]I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you.
Let pretend that I...

Romy I see were you are going With this horn worship for midbass. It is the correct thing to do "But you still will not be happy with the outcome because it does no go low enough. You will not be happy with 60hz. Then you will need something that ...

By “midbass horn” I’m talking about a horn with about a flare frequency of about 60 Hz, to use with Fane 8” drivers, to start with.
(Was planning to use this horn from wherever it sounded best, trying for around 80 Hz to ~35...

Romy, do you think there is enough of a chance Fane's new studio 5 incher (http://www.fane-acoustics.com/pdfs/Studio_5M.pdf) could be driven down far enough to be worth trying out for an upper midbass horn (120Hz)? ...

I have been running around this design for a couple of months...I re-designed it just now to change some numbers according to your post. The main idea is to have a lot of posibilities in a huge horn:It is formed by conical sectors th...

Here is an idea that I partially like. I make the horn “invisible” by using a full height of a room; I made just 12” as an example.
This is basically the regular J-horns but it is INVERTED and has a few advantages over what peop...

Thinking further about my "Hanging" inverted Midbass J-horn presented above I asked myself: where is to cut this 12’-13’ horn hypothetic horn. Initially I thought to do it in order to keep the parts smaller to be able to fit them through the doors an...

[quote user="Romy the Cat"] Still, I did not mention the most important thing about my new midbass horn. This most important and the most astonishing new characteristic of Sound I did not pursue and I got it purely accidently. I did not talk ab...

Listening my new midbass horn, just left channel for now, I would like to share my observation so far about sonic result of the project. Generally the sonic result of the project have exceed my expectations, however not always in the directions ...

Yes, it is certain in what I proposed there is majored disadvantage of having a suspended floor. A suspended is like a bad turntable – no matter what you do you would never be able to get proper lower octave. The idea to have horn firing from ro...

[quote user="Romy the Cat"]The subject of midbass nasal sound is very interesting. In addition to all OTHER aspects that might lead to midbass honk I would like to note that there is one that is in my view greatly overlooked – the precision of re...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

[quote user="el`Ol"]Romy, are you going to verify the decision of using fragile vintage drivers?E.g. by trying JBL midbass drivers?They would be closer to the design philosophy of the Fane Studio 8M.http://www.jblpro.com/components/maxout.htm#2020H[/...

I want to share what I feel is a good application of an injection channel, as introduced by Romy. But this is different and also useful and i can tell you it works and very well. Of course, I do not recommend to use this application in the same exact...

Discussing the Jessie project we multiple times mention the idea of the large midbass horn handing above MF section. Where else the 7”-9” might be positioned? The rational was to have it positionally contra-react the output of the upperbass horn. It ...

John, I disagree.
No one deny the importance of harmonics and you are right saying that “If a speaker does not reproduce the harmonics correctly, then the tone is not reproduced correctly.” However you are talking about a complete speaker, not...

This is a very important question as since very beginning of the projects it was questionable if I would be able to get away with the back/top firing position of my midbass horn. So, as now, when the midbass horn project is over and horns fully i...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

Ok, I will share with you some ideas that I have in my head how to deal with horn decay asymmetry. They are in a way the further development of the Haralanov’s idea of acoustic diode – the brilliant concept from my point of view.
Before I will...

[quote user="T3GGG"]Romy, what is your thought on using a Tractrix flare on a Midbass horn, Fc 140HZ then maybe a Le Cleah horn above, say 400hz. To me this looks on paper to be the best of both worlds and avoids the 1metre plus midbass Le Cleac'h ho...
